Abstract: Techniques are described for allocating resources to a task from a shared hardware structure. A plurality of tasks may execute on a processor, wherein the processor may include one or more processing cores and each task may include a plurality of computer executable instructions. In accordance with one technique for allocating resources to a task from a shared hardware structure amongst multiple tasks, aspects of the disclosure describe assigning a first identifier to a first task from the plurality of tasks, associating a portion of the shared hardware resource with the first identifier, and restricting access and/or observability for computer executable instructions executed from any other task than the first task to the portion of the hardware resource associated with the first identifier.

Abstract: Techniques are described for injecting noise in a timer value provided to an instruction requesting the timer value. A plurality of tasks may execute on a processor, wherein the processor may comprise one or more processing cores and each task may include a plurality of computer executable instructions. In accordance with one technique for injecting noise in the timer value, a request for a first timer value is received by one or more computer executable instructions belonging to a first task from the plurality of tasks, and in response, a second timer value is provided to the first task instead of the first timer value, wherein the second timer value is derived from the first timer value and a random number.

Abstract: Techniques are described for accumulating unused computing resources. The techniques may involve associating, with a task, a baseline amount of a computing resource for each time interval of a predetermined number of time intervals, and monitoring a consumption of the computing resource by the task in each time interval. Resource credits can be accumulated based on an unused amount of the computing resource during at least some of the time intervals. When a workload of the task consumes more than the baseline amount of the computing resource, the accumulated resource credits can be applied to allocate an additional amount of the computing resource to the task. A proportionate additional amount of a memory resource can also be allocated to the task.

Abstract: Techniques are described for injecting noise in a timer value provided to an instruction requesting the timer value. A plurality of tasks may execute on a processor, wherein the processor may comprise one or more processing cores and each task may include a plurality of computer executable instructions. In accordance with one technique for injecting noise in the timer value, in response to a request for a timer value, an artificial and indeterminate amount of delay may be introduced before accessing of the timer value from the hardware timer. In one implementation, access to the hardware timer for the timer value may be gated by one or more artificially injected micro-architectural events.

Abstract: Techniques are described for accumulating unused computing resources. The techniques may involve receiving a request to execute a task for a tenant on shared hardware resources and assigning a task identifier to the task. A baseline resource credit per time interval of a computing resource can be determined based on a service level agreement associated with the tenant. The techniques may further involve monitoring a performance counter associated with the computing resource to determine a utilization amount of the computing resource by the task during a first time interval, determining an unused amount of the computing resource in the first time interval based on a difference between the utilization amount and the baseline resource credit and incrementing a resource credit balance associated with the task identifier by the unused amount of the computing resource.
